Annoyingly I can't seem to find a dealer for the G&L in the UK, and routing the body might be a bit of a faff... Currently looking at either Babicz or Schaller 3D-4 (though I'm not sure if the latter is lefty friendly due to the width of the rollers, not sure if anyone here who has one can confirm how hard it would be to swap those around?)
On a separate note this is really interesting! My Lusithand pre just arrived, but the design doesn't have a pick attack mode, just a boost in the resonance of the cutoff. I'm wondering how tricky it would be to implement, its made slightly trickier by the fact that the circuits are gooped and that my pickups are wired new way 1HBPS... Might message Nuno to see!
The rest of my build isn't looking like its going to be finished for another month or so so going to have to wait to hear how it all sounds. Will post some sound clips when its up and running though!
